Help me please..Same Buyer Scamming me

A few weeks ago I sold a Juicy Couture Daydreamer bag..It was auction style and at the end of the auction buyer never paid..I kept getting emails she would promise to pay. Finally after a few days her payment came in..I was happy and just glad to be done with it...Before I could ship Pay pal notified me there was a problem with this buyer and her payment. They took my funds right back out and did an investigation..All the while my buyer never contacted me. I tried to email her but no response..Pay pal finally decided that I need to refund her and gave me back my listing fee's

Long story short I listed the bag back up auction style again.It ended this eveing with a buyer with zero FB winning the auction..No payment yet but the name on the invoice looked awfully familiar..I double checked and it was the original buyer.

Now I don't know what to do..She must have several ebay accounts..Also from her FB it looks as though she does this all the time. NOW WHAT??

She has already cost me weeks with this bag..I had genuine bids as well..I am so mad!!!!
